[Taliesin]

I dont want to start guest with this option, is there a way to remove it ?
cant set 0 for cores and sockets via web

I dont want to start guest with this option.

Why not?

Cpu load is half a size when not using smp on windows2008 guest.

Cpu load is half a size when not using smp on windows2008 guest.

Just assign 1 core and 1 socket - that should be the same as not using the smp parameter?

 

[Taliesin]

It's not, guest hangs during first boot , have to stop it via web or cmd line and boots correctly during second boot, but performace is degraded, with 1 socket and 4 cores it boots without problem, without -smp also no problems with boooting

The bigest flaw in proxmox that you can't control all kvm options.

It's not, ..

I just re-read the source code - starting without -smp is the same as assigning one socket with one core - I cant see any difference?

 

[Taliesin]

But my guest hangs with and dont without

What is the output of

# pveversion -v

The bigest flaw in proxmox that you can't control all kvm options.

did you know the "args" option in qm?

 

[tom]

ok, got all infos. i tested a clean install of win2008-32 with 1 vcpu (ide) - and it hangs on first boot like you described.

but it also hangs if I remove the '-smp sockets=1,cores=1' - so no difference here.

I also tested the win2008r2 (64), no problem here. so I have no solution for this issue with the old windows server.

 

[Taliesin]

Thx for info , an question can i expect solution or you just dont support win2008-32 ?
i know the about qm args
but how to set automaticaly all changes when backuping every night guest image

win2008-32 works fine, only the first boot hangs.

i know the about qm args
but how to set automaticaly all changes when backuping every night guest image

I do not understand this question. just add the args in the VMID.conf file.

 

[Taliesin]

And going back to main question , I ran some tests and for me it hangs only when i have -smp enabled without guest starts with no problem (20 stops and starts)
I dont want to start guest with -smp. Is there a way to do this , comment lines in qm.pm or anything else.
